The smallest Polish sole traders and micro companies; all Polish businesses regarding penalties.

Since 1 April 2026 all businesses in Poland must issue B2B invoices through the National e-Invoicing System (KSeF) in the FA(3) XML schema; the system assigns the legal invoice number and the buyer receives it via KSeF. Only micro-entrepreneurs with monthly sales up to PLN 10,000 (gross) have until 2027. Paper and PDF invoices are no longer valid B2B invoices.
Every VAT-registered business in Poland, including foreign companies with a Polish fixed establishment.
